A bicyclo[3.1.1]heptano[4,3-c]pyrazole derived chiral auxiliary for dipolar cycloadditions

Starting form naturally occurring (S)-cis-verbenol 1 and (1R)-(-)-myrtenol 2, we synthesised enantiopure bicyclo[3.1.1]heptano[4,3-c]pyrazole derivatives 7 and 8 via a stereoselective nitrilimine cycloaddition as the key step. The effectiveness of the abo
